COLLAPSIBLE GATE.

/ Application filed July 8, 1905. Serial No. 268.828.

To ctZZJwhOm/ it Heap/concern.

Be it known thatI,*GHAnLEs*MEYnR,a citizen of theUni-ted States,residing at New York, in the county of' New York and State of New York,have invented certain new and useful Improvements in Colla sible Gates,'of cation, such as artto which it which the following is a speci willenable those skilled in the appertains to make and use the same? A animproved collapsible gate articularly designed for use on elevated andother cars, but which may be used wherever gates of this class aredesired, a further object being to provide a gate of the class specifiedwhich is simple in construction and operation and provided withconvenient and efiective devices for opening and closing the ate and forholding it in both the open and c osed position.

This invention is an improvement on that described and claimed in theUnited States Patent No; 730,036, granted to me June 2, 1903, and theinvention is fully disclosed in the following specification, of whichthe accompanying drawings form a part, in which the separate parts of myimprovement are designated by suitable reference characters in each ofthe views, and in which-- Figure 1 is a side view of the frame of myimproved gate and showing the gate collapsed; Fig. 2, a view at rightangles to Fig. 1 and looking in the direction of the arrow as of saidfigure; Fig. 3, a side view of the gate expanded, the support only beingshown in section; Fig. 4, a partial section on the line 4 4 of Fig. 1.

In the practice of my invention I provide a suitable support, which mayconsist of the end of a car or of a stationary frame, or of a panel of afence with which the gate in ractice may be connected, but which, as sown in the drawings, consists of a frame or support composed ofvertically-arranged side members a and 1), horizontal top and bottommembers a and diagonally-arranged members a, The vertically-arrangedside member b in the form of construction shown consists of a centralmember 5 and two side members 5 connected by transverse members b, andthe part1) is made double in the form of construction shown and isprovided at the top with a loop or bend b The gate proper is connectedwith the side member b of the main frame and. consists of an end member0 and lazy-tong levers d, which are connected with said end member 0 attwo osed'olf'tv'vo parts an'd'the The ob ect of this invention 18"toprovide i points, as shown at (2 and with the central part 'b of themain frame at two different points,*as shown at'd 'and d,"andtlreconnec. tion at (Wis made by means of a slidingblock d9; memed'tetween as separate parts of the centrarmembemrof thj'es'ide'meinb'er b of the frame or Suppzirt; and it will alp'fbeseenthatthe and member 0 of the gateiscoin- L 'c' or in ectioi'fof theair-tong revered therewith" at thebotto'm thereof is made by means of asliding block d Mounted horizontally in the top portion of the frame orsupport is a rod 6, on the end of which adjacent to the gate is atubular shaft 6?, provided with a gear-wheel e which 0 erates inconnection with a larger gear-w eel 6 mounted on the part b of the frameor support and in a vertical plane parallel with the plane of the gate,and the wheel 6 is provided with a crank-link e which is connected at cwith the'lazy-tong levers of the gate, and the wheel (2 is provided witha lug or projection 6 which operates in connection with the crank-link 6The end of the rod e opposite the tubular shaft (5 passes through a tubef, rigidly secured to the frame or support and provided with a sleeve fon which is mounted a bevel gear-wheel f and the tubular shaft 6 isprovided at the end thereof opposite the gearwheel 6 with a bevelear-wheel f", which meshes with the wheel and the wheel f 3 is providedwith a crank g, having a handle g, as clearly shown in Figs. 1 and 2.

The operation is as follows: Suppose the gate to be in a collapsedposition. In order to extend the gate, as shown in Fig. 3, the wheel f 3is turned to the right, as indicated by the arrow y in Fig. 1. Thisoperation turns the wheel 6' to the left, as indicated by the arrow y inFig. 2, and the gate is extended, as shown in Fig. 3. When it is desiredto collapse the gate, the wheel f is turned to the left, and thisoperation turns the wheel a to the right, as indicated by the arrow (1in Fig. 3, and the gate is thrown into the collapsed position, as shownin Figs. 1 and 2. In the operation of closing or extending the gate, asshown in Fig. 3, the lug or projection e strikes the crank-link e whenthe gate is fully closed or extended, and this prevents the furtherturning of the wheel a, together with the further turning of the wheelse and f and the position of the pivotal connection of the crank-link cwith the wheel 6 is such that said crank-link forms a lock for the gateand the gate cannot be collapsed or opened without turning the wheel f 3to the left.

The lug or projection e on the wheel a", in combination with thecrank-link e constitutes the chief feature of this invention and distinuishes the same from that described and c aimed in the patenthereinbefore-referred to.

Having fully described my invention,wh at I claim as new and desire tosecure by Letters Patent, is-

"The combination with a support of a collapsible gate consisting oflazy-tong levers and an end member, the lazy-tong levers being connectedwith the support and the end member of the gate, a shaft mounted on thesupport at right angles to the gate and provi ed with a gear-wheel,another gear-wheel mounted on the sup ort and operating in connectionwith the st-named gear-wheel,

a crank-link connected with the last-named gear-wheel and with thelazy-tong levers of the gate and adapted to open and close the gate,said last-named gear-wheel being also provided with a lug or projectionwhich operates in connection with the crank-link, and means foroperating said shaft, consisting of a beveled gear-whee1 mounted on thesup port, a beveled gear-wheel connected with said shaft and a crankconnected with the first-named bevel gear-wheel, substantially as shownand described.

In testimony that I claim the foregoing as my invention 1 have signed myname in presence of the subscribing witnesses, this 7th day of July,1905.
